established. From these cultures twonewpentacyclictriterpenes, 3-epi-pomolic acid 3alpha-acetate (3alpha-acetoxy-19alpha-hydroxyursa-12-en-28-oic acid) (1) and baloic acid (3alpha-acetoxy-19alpha-hydroxyursa-12,20(30)-dien-28-oic acid) (9), were isolated. The former was also obtained from P. pendula natural roots, together with another twonewpentacyclictriterpenes, 3-epi-pomolic acid (3alpha,19
